    Description / Table of Contents: Resume Cet article présente une approche à la fois expérimentale et numérique pour ordoner les nombreux résultats, parfois contradictories, reflétant la caractérisation de l'interface béton/acier collé à l'époxy. Sur la base des données fournies par une éprouvette spécialement conçue en 1/2 poutre et des résultats expérimentaux apportés par d'autres géométries d'éprouvettes, combinés avec leur idéalisation respective par la méthode non-linéaire des éléments finis, on suggère, pour l'interface acier—adhésif—béton, une loi de rupture Mohr—Coulomb modifiée. On peut alors utiliser la simulation de ce comportement (éléments finis) d'une poutre en béton renforcé d'une plaque.
    Notes: Abstract An experimental—numerical approach is presented to rationalize the plethora of results, sometimes contradictory, reflecting the chrracterization of an epoxy bonded steel—concrete interface. Based on data from a specially designed half-beam specimen and experimental results from other specimen geometries, combined with their respective nonlinear finite element idealizations, a classical Mohr—Coulomb failure law together with a tension cut-off are suggested for the steel—glue—concrete interface. This description can then be used in a finite element simulation of a plated reinforced concrete beam.

    Notes: This paper deals with a finite element formulation and solution of the boundary value problem of a concentrated force acting on a semi-infinite micropolar solid. A stiffness matrix is derived for a flat micropolar rectangular element in a plane state and use is made of this element to solve the case of the semi-infinite micropolar solid both in a state of plane stress and plane strain. An immediate application of the plane strain case is the important practical problem of a long line load acting on a soil mass which may be simulated as a micropolar body.

    Notes: The ultimate strength of polymer concrete was investigated utilizing epichlorohydrin/bisphenol A-type epoxy resin. Parameters were tested in an effort to conclude how variation of a specific parameter would affect the compressive strength of the polymer concrete. The parameter testing included studies to determine the effect of the polymer loading; the catalyst; the exothermic reaction; aggregate type, gradation and moisture content; curing age; and aggregate additives of portland cement and lime-stone powder.
